ABOUT THIS IMAGE:

This is a composite image of galaxy cluster MS0735.6+7421, located about 2.6 billion light-years
away in the constellation Camelopardalis. The image represents three views of the region that
astronomers have combined into one photograph. The optical view of the galaxy cluster, taken by
the Hubble Space Telescope's Advanced Camera for Surveys in February 2006, shows dozens of
galaxies bound together by gravity. Diffuse, hot gas with a temperature of nearly 50 million degrees
permeates the space between the galaxies. The gas emits X-rays, seen as blue in the image taken
with the Chandra X-ray Observatory in November 2003. The X-ray portion of the image shows
enormous holes or cavities in the gas, each roughly 640,000 light-years in diameter  nearly seven
times the diameter of the Milky Way. The cavities are filled with charged particles gyrating
around magnetic field lines and emitting radio waves shown in the red portion of image taken
with the Very Large Array telescope in New Mexico in October 2004. The cavities were created by
jets of charged particles ejected at nearly light speed from a supermassive black hole weighing
nearly a billion times the mass of our Sun lurking in the nucleus of the bright central galaxy. The
jets displaced more than one trillion solar masses worth of gas. The power required to displace
the gas exceeded the power output of the Sun by nearly ten trillion times in the past 100 million years.
